在webview.goBack（）上调用“shouldOverrideUrlLoading”方法

Question

I'm loading all my pages inside shouldOverrideUrlLoading method on webview (mainly to track the current page url and do some modifications).

My problem is that the back button ( eg: webview.goback() method ) bypasses the above function.

Is there any way i can explicitly call both the goback() and shouldOverrideUrlLoading() methods.

public boolean shouldOverrideUrlLoading(WebView view, String url){
//get current url and do some modifications to html}

public boolean onKeyDown(int keyCode, KeyEvent event) {
     if ((keyCode == KeyEvent.KEYCODE_BACK) && web1.canGoBack()) {
         webview.goBack();  
         return true;
      }
      return super.onKeyDown(keyCode, event);
}

Looking at your code seems like once the shouldOverrideUrlLoading method is called based on some logic for a specific URL Action you need the Webview go back method. I would suggest you to use the following method inside the activity:

@Override
public void onBackPressed() {
    if ((keyCode == KeyEvent.KEYCODE_BACK) && web1.canGoBack()) {
        webview.goBack();
    } else {
        super.onBackPressed();
    }
}

which does exactly the same as onKeypressed. (Used onBackPressed instead of onKeypressed but write this code inside the Activity class but not inside the custom WebViewClient .

Call the onBackPressed() inside your shouldOverrideUrlLoading . Try this, should work.
